It should be understood that although the above-described combination sunscreen and insect repellant compositions and/or methods are described as “comprising” one or more components or steps, the above-described combination sunscreen and insect repellant compositions and/or methods may “comprise,” “consists of,” or “consist essentially of” the above-described components, features or steps of the combination sunscreen and insect repellant compositions and/or methods. Consequently, where the present invention, or a portion thereof, has been described with an open-ended term such as “comprising,” it should be readily understood that (unless otherwise stated) the description of the present invention, or the portion thereof, should also be interpreted to describe the present invention, or a portion thereof, using the terms “consisting essentially of” or “consisting of” or variations thereof as discussed below.

As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having,” “contains”, “containing,” “characterized by” or any other variation thereof, are intended to encompass a non-exclusive inclusion, subject to any limitation explicitly indicated otherwise, of the recited components. For example, a combination sunscreen and insect repellant composition and/or method that “comprises” a list of elements (e.g., components, features, or steps) is not necessarily limited to only those elements (or components or steps), but may include other elements (or components or steps) not expressly listed or inherent to the combination sunscreen and insect repellant composition and/or method.

As used herein, the transitional phrases “consists of” and “consisting of” exclude any element, step, or component not specified. For example, “consists of” or “consisting of” used in a claim would limit the claim to the components, materials or steps specifically recited in the claim except for impurities ordinarily associated therewith (i.e., impurities within a given component). When the phrase “consists of” or “consisting of” appears in a clause of the body of a claim, rather than immediately following the preamble, the phrase “consists of” or “consisting of” limits only the elements (or components or steps) set forth in that clause; other elements (or components) are not excluded from the claim as a whole.

As used herein, the transitional phrases “consists essentially of” and “consisting essentially of” are used to define a combination sunscreen and insect repellant composition and/or method that includes materials, steps, features, components, or elements, in addition to those literally disclosed, provided that these additional materials, steps, features, components, or elements do not materially affect the basic and novel characteristic(s) of the claimed invention. The term “consisting essentially of” occupies a middle ground between “comprising” and “consisting of”.

Further, it should be understood that the herein-described combination sunscreen and insect repellant compositions and/or methods may comprise, consist essentially of, or consist of any of the herein-described components, features and steps, with or without any additional feature(s). In other words, in some embodiments, the combination sunscreen and insect repellant compositions and/or methods of the present invention do not have any additional features other than those described herein, and such additional features are specifically excluded from the combination sunscreen and insect repellant compositions and/or methods. In other embodiments, the combination sunscreen and insect repellant compositions and/or methods of the present invention do have one or more additional features other than those described herein.

While the specification has been described in detail with respect to specific embodiments thereof, it will be appreciated that those skilled in the art, upon attaining an understanding of the foregoing, may readily conceive of alterations to, variations of, and equivalents to these embodiments. Accordingly, the scope of the present invention should be assessed as that of the appended claims and any equivalents thereto.
